Title: Process for the preparation of cheese flavour compositions
Inventor: LASHKARI BANOO ZERXES
IPC: A23L27/24
Filed: 1964-11-25
Abstract: A process for the preparation of a cheese flavour composition involves growing micro-organisms capable of producing a cheese-flavour, in a high-fat medium.  The high-fat medium, containing 30-80% fat, may be the cream from the milk of cows or buffaloes, or coconut or soya-bean oil.  Preferred micro-organisms are Penicillium sp. (especially Penicillium roqueforti), Candida lipolytica, Oidium lactis, Cladosporium sp. (especially Cladosporium butyri), Micrococcus sp. and Lipomyces sp. Immediately before transfer to the high-fat medium the micro-organisms may be grown in a subculture medium low in protein (0.1-3.0% protein) held at a temperature between 20 DEG  and 40 DEG  and at a pH of between 4 and 5.  Th inoculated high-fat medium is incubated at a temperature between 25 and 40 DEG C., usually for about 48 hours.  The cheese flavour composition obtained may be sterilized by heating or incorporated directly into a foodstuff in a small proportion. According to an example, whey broth medium (pH 4.5) was inoculated with a vigorously growing culture of Candida lipolytica previously grown for 48 hours on tomato tryptone agar, and silicone oil was added to the broth in order to control foaming.  After 48 hours cells of Candida lipolytica were inoculated into sterile buffalo cream containing 50% fat.  After a further 48 hours, the inoculated cream had acquired a highly cheesy aroma and was used as the basic material for preparing cheesy ghee.  According to a further example, cells of Candida lipolytica from agar slants were inoculated directly into sterile cream and incubated at 30 DEG C. for 48 hours.  After this time, the cream was heated at 80 DEG C. for 30 minutes.  It was then cooled to 40 DEG C. and spores of Penicillium roqueforti were added. The cream was further incubated for 24 hours.  At the end of this time a strong blue-cheese flavour had developed and the cream was spray-dried and stored.

Wood chips and steam under pressure are mixed in unit 72, provided with gas-exhaust means, the mixture is fed to a continuous digester 75, supplied with aqueous cooking liquor and additional steam as indicated, and the digested pulp is continuously discharged through conduit 73 into washer 191, where it is washed with fresh water. Spent cooking liquor is continuously discharged from the digester through pipe 76, and the spent liquor enters flash tank 77 maintained at a pressure of about 18 psig. The flashed vapours are fed through pipe 85 to the mixing unit. The spent liquor flowing out of tank 77 through pipe 79 enters flash-tank 80, which may be maintained at subatmospheric pressure, where further flashing occurs. The spent liquor from tank 80 is pumped to storage tank 441; and the dilute liquor from washer 191 is also forwarded to tank 441. Weak liquor is pumped through pipes 401, 4011 from tank 441 to evaporators 351, 3511; and the concentrated liquor, withdrawn via pipes 461 and 4611, may be either returned to tank 441 or discharged via pipe 541. The vapour from flash-tank 80 is supplied to the heater 371 of evaporator 351; and part of the vapour evolved in evaporator 351 is used as heating-medium for evaporator 3511. A stream of water, introduced through pipe 87, is heated in heat-exchanger 86 by vapours from evaporator 35<11>. The water is then further heated in heat-exchanger 91 by vapours from evaporator 351. A plant is also described which incorporates continuous and batch-type digesters in combination. In a modified procedure for utilizing the heat contained in the vapour flashed from the spent digester liquor, the vapour is condensed by jets of water in a direct-contact condenser, and the hot water so obtained is collected in an accumulator of appreciable depth. The cooler water in the lower part of the accumulator is recycled to the jets of the condenser. Hot water withdrawn from the upper part of the accumulator is used as heating-medium for the evaporator in which the dilute spent liquor is concentrated. Alternatively, hot water, withdrawn from the upper part of the accumulator, is passed to a flash tank, and the flashed vapour is used as heating-medium for concentrating the weak spent liquor.

Title: Process for preparing the n-monomethylamide of o,o-dimethyldithio-phosphorylacetic acid
IPC: C07F9/165
Filed: 1962-12-24
Abstract: The N-monomethylamide of O,O-dimethyldithiophosphoryl acetic acid is obtained by amination of an alkyl or aryl ester of O,O-dimethyl-dithiophosphorylacetic acid with monomethylamine, the temperature in the reaction mass being maintained uniformly constant by evaporation and condensation of a single substance or a mixture of substances which does not or do not react with the reactant substances nor with the end product and have a boiling point under the working conditions of from -15 DEG C. to +10 DEG C., preferably near 0 DEG C., e.g. +2 to -2 DEG C.  The working pressure may vary between 20 mm. Hg. and 30 atmospheres.  The monomethylamide product may be insoluble in the single substance or in the mixture and the reactants and the by-products formed may be soluble in the single substance or in the mixture. Specified substances or mixtures which may be employed are butane, CCl3CF3, a mixture of 79.5% (or 90%) CCl3F and 20.5% (or 10%) CCl2F2 by volume, methylcyclopropane, dichlorodifluoromethane, propane, perfluorobutane, 2-methylpropane, C2H5Cl and CH3Cl. It is preferred to use butane or the mixture of 79.5% CCl3F and 20.5% CCl2F2.  In one embodiment the methyl ester of O,O-dimethyldithiophosphorylacetic acid is reacted with monomethylamine in aqueous solution in the presence of liquid butane in a vessel fitted with a stirrer and refluxing cooler wherein liquid ammonia is circulated, the amine being introduced gradually.  The temperature is maintained at 0 DEG C. by the boiling butane and the N-monomethylamide product which is gradually formed separates in the crystalline state.  At the end of the reaction a semi-solid mass has formed and this may be made fluid by adding water cooled to near 0 DEG C.  The excess amine is then neutralized with dilute H2SO4 kept at 0 DEG C. and the finished product separated by filtration, e.g. centrifugation. Alternatively, the butane may be removed by distillation of the water-butane suspension and the residue centrifuged to recover the product. The above specified mixtures of CCl3F and CCl2F2 may be used instead of butane in an analogous manner.  Specification 926,715 is referred to.
